Determining whether an Employer Identification Number (EIN) is active is essential for business owners, accountants, lenders, and anyone involved in verifying a company’s tax identity. This list covers 10 reliable ways to check the status of an EIN, providing practical steps and resources you can use to confirm if an EIN is currently valid and in use. Whether you need to verify a vendor, confirm your own EIN status, or ensure compliance, these methods will guide you through the process.
1. Contact the IRS Business & Specialty Tax Line
The IRS Business & Specialty Tax Line at 1-800-829-4933 is the primary resource for inquiries about EINs. You can call this number to confirm if an EIN is active, but you must be authorized to receive the information, typically as the EIN holder or a responsible party. The IRS representatives can verify EIN status and provide guidance on EIN-related questions during business hours, Monday through Friday.
2. Review Your EIN Confirmation Letter (CP 575)
When the IRS issues an EIN, it sends a confirmation letter known as CP 575. This letter confirms the EIN and its activation for tax purposes. If you have this letter, it serves as proof that your EIN is active unless you have received official notice of cancellation or revocation from the IRS. Keep this document safe as it is often required for financial and legal transactions.
3. Check the IRS EIN Online Assistant Tool
The IRS offers an EIN Online Assistant primarily for applying for new EINs, but it does not provide a tool to check EIN status publicly due to privacy rules. However, you can use the tool to verify if an EIN is valid when applying for a new number or if you are unsure about your EIN. For status confirmation, direct IRS contact is necessary.
4. Verify Through the Secretary of State’s Business Entity Search
Many states maintain online databases where you can search business entities by name or EIN. Although these databases do not always show EIN status directly, an active business registration often indicates an active EIN. If the business is listed as active or in good standing, it is likely the EIN is also active, especially if the business is required to file state taxes.
5. Use Third-Party Business Verification Services
Several commercial services, such as Dun & Bradstreet, Experian Business, and LexisNexis, offer business verification that includes EIN validation. These services aggregate public records and financial data to confirm if an EIN is active and associated with a legitimate business. While many require a subscription or fee, they provide detailed reports useful for lenders and vendors.
6. Check Your Business Tax Returns
Your filed business tax returns (e.g., Form 1120, 1065, or Schedule C) include your EIN and demonstrate active tax reporting under that number. If you have filed returns recently using the EIN, it indicates the EIN remains active. Failure to file for multiple years may lead to IRS deactivation or revocation of the EIN.
7. Review IRS Notices About EIN Status
The IRS sends formal notices if an EIN has been deactivated or revoked, often due to inactivity or noncompliance. If you receive a letter indicating EIN cancellation, it confirms the EIN is no longer active. Conversely, absence of such notices, combined with ongoing tax filings, suggests the EIN remains valid.
8. Consult Your Accountant or Tax Professional
Accountants and tax professionals who handle your business filings have access to IRS transcripts and documentation that indicate EIN status. They can request EIN verification letters (Form 147C) from the IRS on your behalf, which serve as official proof of an active EIN. They also ensure compliance with IRS regulations related to your EIN.
9. Request an EIN Verification Letter (Form 147C) from the IRS
Form 147C is an official IRS document confirming your EIN and its status. You can request this letter by calling the IRS Business & Specialty Tax Line or by written request. It is commonly used to verify EINs for banking, contracts, and tax purposes, and it confirms the EIN is active and associated with your business.
10. Check Your Bank or Financial Institution Records
Businesses typically provide their EIN to banks to open accounts or apply for loans. Banks verify EINs with the IRS during account setup. If your bank has accepted your EIN for business accounts or loans, it is an indication the EIN is active. You can also ask your bank to confirm the EIN status as part of their due diligence process.
How to Choose
When deciding how to verify if an EIN is active, consider your role and access level. If you are the EIN holder, directly contacting the IRS or requesting Form 147C is the most authoritative method. For third parties, state business registries and reputable verification services offer reasonable confirmation without violating privacy rules. Your choice depends on whether you need official IRS confirmation, quick public data, or detailed business reports. Also, consider cost and convenience: IRS phone verification is free but requires authorization, while third-party services may charge fees but provide comprehensive data.
